First Claim
Patent Images
1. A cable for reducing crosstalk during ultrasound continuous wave operation, the cable comprising:
- a first group of ultrasound signal conductors;
a second group of ultrasound signal conductors, the ultrasound signal conductors of the second group different conductors than the ultrasound signal conductors of the first group; and
a conductive separation layer separating the first group of ultrasound signal conductors from the second group of ultrasound signal conductors.

Abstract
Methods and systems for reducing crosstalk during continuous wave ultrasound data acquisition are provided. A conductive layer electrically shields groups of transmit conductors from groups of receive conductors to reduce noise susceptibility. Mutual coupling during continuous wave Doppler imaging is avoided by providing a shield between or around different groups of conductors. A shielded cable is provided within another cable.
